====== TTP01-05 The determination of $V_{ub}$ from inclusive semileptonic $B$ decays ====== The hadronic mass distribution in semileptonic B-meson decays can be used for extracting the charmless part and thus determining the |V_ub/V_cb| ratio. We take into account first-order perturbative as well as non-perturbative QCD corrections. The sensitivity to model assumptions is studied and an estimate of the remaining uncertainties is performed. |**M. Jezabek, T. Mannel, B. Postler, P Urban** | |** Phys. Lett.
